It's definitely a grass plant.Looks like what we used to call sand burs when I was a child. Nasty things that would stab into your foot when you walked barefoot....
Sounds like you have an annual species of it. I thought that there was only one species. I don't know how many species we have here in the states, but it appears there are 25-26. I also don't know if we have both annual and perennial species here. No wonder the range map I found didn't make sense based on my observations. Had to be a different species.Sand burs and I am dealing with them now, have to get them early spring. MSMA is what I used last year but to late. I still have them, work with my extension agent to wipe them out come spring. They will stick to your tractor tires and replant them all over your place. So I decided to not mow that area till after I spray them next spring, yes they are a grass and yes it is NASTY
I commend and thank you for your efforts. I am familiar with this vegetative "nasty". It got introduced to the Colville Reservation when someone cut corners and bought and 'planted' seed that had not been certified on about 2,500 acres on a rather steep slope. There were a few law suits involved, a couple agencies with marred reputations, and a couple individuals who got to put the word "former" before the word employer when they describe their employment status.My guess is you are seeing them along the road, because the grader wasn't properly cleaned, and the seeds were transported in by the grader. This is a pet peeve of mine.
We first got Yellow Starthistle on our ranch after a fire back in 1992. It started when the neighbors burn got away from them. It came in on us and they used a Cat hauled in from another location to build a fire line and to repair the roads they damaged fighting the fire. We first saw them along the edges were the Cat had scraped back vegetation and topsoil. We were too slow in initially going after them and by about 1997 we had acres of them spread over miles of the ranch. We have been agressively fighting them ever since. They are in pretty decent control on our ranch now, as a result of an immense amount of work each year, spent spot spraying. We walk miles carrying heavy pack-back sprayers, up and down steep hills, inaccessible except on foot or horseback. Unfortunately we will never be done with them, because of infestations on neighbors. The neighboring rock quarry has a bad infestation of various thistles and Poison Hemlock, and they don't bother to do anything about it. I expect seeds are spread throughout the county, when loads of rock leave the pit. I wish there was some sort of rule that required these quarries to spray their weeds, so they wouldn't be responsible for transferring seed all over the county.
That has become all too common. Someone sounds the alarm about a 'few new weeds', a feeble attempt is made to control them, and then they turn into an "uncontrollable, raging forest/range fire". I haven't seen or used the term in some time, but noxious weeds really are a "silent wildfire".There was a program through the Douglas County Soil and Water Conservation District back in about 1997 that provided help in controlling Starthistle. That year they provided labor and we paid for herbicide. Best deal we have ever made. We have continued to follow up spraying on our own, every year since. At one time the DCSWCD tried to push through some regulations requiring the quarries to provide clean rock. It was a voluntary program and pits that participated got a label. Something like "weed free quarry". I don't remember the exact wording. Since it was going to cost them money and there was no penalty for not doing it, I don't think any ever participated. The DCSWCD went through a number of changes in personnel since then and was mostly shut down for the two years of Covid. I think the whole program was eventually dropped, but I could be wrong.
I think the ODA has pretty much given up the fight. I do talk to the local weed specialist from the ODA from time to time. They have moved their funding to weeds they have potential to control. Since 1992 yellow Starthistle has moved up from California and become so prevalent in certain areas of Southern Oregon, that control seems out of reach.
